Polychaete

I was just reading about a polychaete that uses a sediment trap (a depression in the mud) to feed. When they removed the amount of food in the area, the polychaete would make a larger and larger hole trying to get more food! The scientific term they use is "grossly aberrant pits," and I imagine this worm desperately digging deep pits in the sediment. I caught myself smiling. Science does make me happy.
